[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the motor housing feeding device for motor housing pole shoe pressure welding of the utility model comprises a housing feeding mechanism 2, a copper rod 3, and a lower welding frame 4;

[0026] like Figure 3-5 As shown, the housing feeding mechanism 2 includes a housing feeding frame 21, a housing mounting ring 22, a bushing 23, a housing lifting plate frame 24, a housing moving cylinder 26, and a housing rotating motor 29;

[0027] The casing moving cylinder 26 is connected to the casing loading rack 21; the casing moving cylinder 26 controls the movement of the casing loading rack 21, and a slide rail assembly 28 is provided at the bottom of the casing loading rack 21. The slide rail assembly 28 can be a combination of a linear guide rail and a slider, which guides the movement of the casing loading rack 21, so that the casing 5 on the casing loading rack 21 always moves on the same straight line, avoiding misalignment of the casing 5 and affecting the docking with the copper rod 3.

[0028] A casing lifting cylinder 27 is provided on the top of the casing loading frame 21, and the casing lifting cylinder 27 is connected to the casing lifting plate frame 24; the casing mounting ring 22 is connected to the casing lifting plate frame 24, and the casing mounting ring 22 is connected to the casing rotating motor 29; the casing loading frame 21 is provided with a through hole 212, and the bushing 23 is sleeved on the through hole 212;

[0029] The end of the copper rod 3 close to the housing feeding mechanism 2 is provided with a bushing fitting 31, and the bushing fitting 31 is on the same axis as the housing mounting ring 22 and the bushing 23;

[0030] The copper rod 3 is fixed horizontally on the lower welding frame 4, as shown in FIG. Figure 3 As shown, the lower welding frame 4 is provided with a copper rod connecting hole 42, both ends of the copper rod 3 extend out of the copper rod connecting hole 42, and one end of the lower welding frame 4 close to the pushing mechanism 16 is provided with a copper rod fixing ring 41, and the copper rod fixing ring 41 is supported below the copper rod 3;

[0031] The casing feeding mechanism 2 also includes a casing buffer mechanism 25 , which includes a support plate 252 and a spring member 251 . The support plate 252 is connected to the casing feeding frame 21 via the spring member 251 , and the casing mounting ring 22 is located between the bushing 23 and the support plate 252 .

[0032] The housing 5 is only manually inserted into the housing mounting ring 22, and a part of the housing 5 extends out of the housing mounting ring 22, and its clamping strength is not strong. The housing lifting cylinder 27 pushes the housing lifting plate frame 24 to descend, and the housing 5 in the housing mounting ring 22 is lowered accordingly, and the supporting plate 252 supports the housing 5, so that the housing 5 can be lifted and lowered smoothly. When the housing 5 is lifted by the housing lifting cylinder 27, the spring member 251 can lift the supporting plate 252 to achieve the effect of shock resistance and buffering, so that the part of the housing 5 extending out of the housing mounting ring 22 can also be quickly and smoothly lifted and reset, thereby preventing the housing 5 from being skewed in the housing mounting ring 22.

[0033] A bracket groove 253 is provided on the top of the support plate 252 , and the lifted portion of the housing 5 is wrapped in the bracket groove 253 , further improving the lifting effect of the support plate 252 on the housing 5 .

[0034] The housing loading rack 21 is provided with a limiting groove 211, and the housing lifting plate frame 24 is located in the limiting groove 211. The housing lifting plate frame 24 is lifted and lowered along the limiting groove 211, and plays a limiting role in the lifting and lowering of the placed housing 5, and to a greater extent, avoids the misalignment of the housing 5 caused by the misalignment of the housing lifting plate frame 24, and ensures that the housing 5 can be smoothly docked with the copper rod 3.

[0035] like Figure 2 As shown, since a plurality of pole shoes 6 need to be welded around the inner wall of the housing 5, the housing 5 at the welding position needs to be intermittently rotated by the housing rotating motor 29. The housing mounting ring 22 drives the housing 5 to rotate under the drive of the housing rotating motor 29, and the angle of a single rotation of the housing 5 needs to be controlled.

[0036] The housing lifting plate frame 24 is provided with a sensor 241, and the induction head of the sensor 241 faces the housing mounting ring 22. The angle of the housing 5 required to rotate once is calculated by the number and welding positions of the pole shoes 6 welded to the inner wall of the housing 5, and induction labels are pasted on the corresponding positions of the housing mounting ring 22. The induction head of the sensor 241 senses the label and transmits the signal to the terminal. Through the command of the terminal computer, the housing rotating motor 29 stops operating, thereby accurately controlling the rotation angle of the housing 5 to improve the welding position accuracy of the pole shoes 6 on the inner wall of the housing 5.

[0037] The utility model provides a motor shell feeding device for press welding of motor shell pole shoes, such as Figure 1As shown, the pole shoe 6 is transported to the welding position of the copper rod 3 by the pole shoe feeding mechanism 1; the housing 5 is inserted into the housing mounting ring 22, and the housing 5 is moved toward the copper rod 3 by the housing moving cylinder 26, as shown in FIG. Figure 5 As shown, the housing 5 is inserted into the copper rod 3, the bushing fitting 31 of the copper rod 3 is inserted into the bushing 23, and the two ends of the copper rod 3 are fixed by the copper rod fixing ring 41 and the bushing 23 respectively; then, the housing positioning mechanism 5 presses the housing 5 in the housing mounting ring 22 and resets, the upper electrode of the welding machine is pressed down, and cooperates with the lower electrode of the copper rod 3. During the pressure welding, the housing 5 is lowered a certain distance together with the rhythm of the upper electrode pressing down under the action of the housing lifting cylinder 27, and the inner wall of the housing 5 is welded with the pole shoe 6 on the copper rod 3. After the welding is completed, the housing 5 is rotated by the housing rotating motor 29 to switch another housing welding surface, and the pole shoe feeding mechanism 1 continues to feed, and the next pole shoe 6 is sent into the housing 5, until all the target welding areas of the inner wall of the housing 5 are completed, and the housing feeding mechanism 2 is reset, and the housing 5 is pulled out.
